Last week A-Trak treated us to “Humphrey,” the debut track from his upcoming Federal Reserve EP with Cam’ron that sounded straight out of Dipset’s mid-00’s prime. Because he can switch up sounds like it ain’t a thang, the Fool’s Gold founder is also prepping a project with 1017 Brick Squad producer Lex Luger under the name Low Pros. Here’s the first sample: the haunting “Jack Tripper” featuring rap’s current wavemaker Young Thug and his close collaborator PeeWee Longway. Just like Thug’s “Danny Glover,” this one’s full of quirky quotables: “Three sluts off in my bachelor pad they call me Jack Tripper.”
